Evidence For Evolution
Create on this page a visual representation of your topic. Use definitions, videos, animations, interviews, anything on the web, etc. . that will CORRECTLY convey your evidence for evolution!
1. Darwin's Finches
This explains how the Finches changed over time and adapted to the different living environments when needed to. They would have to get used to feeding off different things and being in different areas of the world and there body would adapt to different places. Darwin didn't realize this until he came home from the Galapagos island and saw the difference in the birds in each area, but realized they were still similar in some ways.
-KATIE HALBRUNER 2. Variation
Here you can see the bill variation in all of the different birds dependign on what they eat or were they are on land. (ground finch, tree finch, warbler finch, etc.) you can see this as well in the picture above. and the three main types of genetic variation: KATIE HALBRUNER 3. Over production and competition Over production occurs when there are too many of one species in an environment. This causes a competition for food, water, and shelter. This competition allows for natural selection to occur by only allowing the “fittest” to survive. The organisms that have the most suitable traits will reproduce and spread their genes on to the next generation.
-Kelly Sinclair
4. Survival of the fittest-This is the idea created by Charles Darwin, the reason behind this was to express his ideas of natural selection. This was the idea that evolution takes place in a species to help them better survive. Only the specific traits that is needed are passed along to the offspring of that specific population. -Brett S.
^^^^^^^^^^^This image shows different builds of birds to better live in their area.
5. Fossils- This is basically the preserved remains of an animal from their environment. By looking at these fossils people can learn about past structures of animals.

6. Analogous Structures
feat ures of 2 different species that are similar in how they function, but the structure of the two features are different. for example a dolphin and a skark are similar in function, built for speed in the water, but they are different as a dolphin is a mammal and a shark is a fish that is constructed out of cartilge.

7. Homologuous Structures
In evolutionary biology, homology refers to any similarity between characteristics of organisms that is due to their shared ancestry.
Taihlor C
8. Vestigial Organs Vestigial organs are structures in an organism that basically have no use. They are historical remnants of structure that had important functions in ancestors thus serving as evidence for evolution.
This picture shows the vestigial structure of a human- the appendix.
-Mike
9. Comparative Embryology
a branch of embryology that deals with similarities and differences in the development of the animals or plants of different orders. alecia 10. Molecular Biology
11. Artificial Selection
The concept allowed Darwin to reason that if artificial selection can achieve so much change in a short period of time, then natural selection should be capable of considerable modification of species over hundreds to thousands of generations. Artificial selection put Darwin’s natural selection into a shorter time frameHumans had the ability to use artificial selection to create different species of dogs from the original, the wild dog. Each would have its own purpose, some for hunting, some for herding, and some even for just companionship, but whatever the purpose of the dog, breeders could choose the dogs which are best for the job that they wanted. Natural selection is occurring with the help of the human.
12. Natural Selection
the organisms and species that survive and reproduce are the sole ancestors to the next generation of living things. Those that die or fail to reproduce will not continue. Natural selection is basically selective breeding happening naturally instead of by a breeder
Ryan H 13. Biogeography
Guided Reading Chapter 22 Darwin
1. What were the two major points of Darwin’s publication “The Origin of Species”? The two major points of the publication of "The Origin of Species" are presenting evidence that many species of organisms currently inhabiting the earth are decendants of ancestral species that were different from modern species, and this is where he stated his theory of natural selection for the first time.
- Sam B
2. Define the following Natural selection- A population can change over generations if individuals that possess certain heritable traits leave more offspring than other individuals who do not possess the favorable traits.
Evolutionary adaptation- accumulation of inherited characteristics enhancing an organism's ability to survive and reproduce in specific environments.
Evolution- a change over time in genetic composition of a population can eventually constitute a new species
Taxonomy- branch of biology concerned with naming and classifying new organisms
3. Detail the impact/position/contribution to evolutionary theory and include a perspective of time in the following: a. Aristotle
b. Linnaeus
c. Cuvier
d. Lyell
e. Lamarck
f. Malthus
g. Hutton
4. How does catastrophism relate to the ideas of gradualism?
5. How did the Voyage of the Beagle impact Darwin’s research?
6. How did Alfred Wallace impact Darwin in his work? Wallace and Darwin shares the same theory of evolution. Wallace contacted Darwin to take a look at the theory and Darwin realized that if he didn't publish his work, he wouldn't get any credit for it. Wallace didn't argue Darwin's creation od the theory, and Darwin produced his book The Origin of Species.
Ashley A
7. What part did adaptation play in Darwin’s thinking?
Darwin believed that through reproduction, the traits that would become most beneficial to the particular species would be adapted and that species would continue to pass on to future generations. Those traits that hindered the species would eventually disappear. Adaptation is vital to species so they can survive in a particular habitat.
Ashley A
8. What did Darwin mean by descent with modification?
Darwin meant that as species moved throughout time, they moved to different habitats and began to accumulate modifications that fit their habitat.
Taihlor C 9. What did Mayr take from Darwin’s work – summarize the observations and inferences.
10. How did the concept of artificial selection impact Darwin’s ideas?
11. What three word phrase summarizes Darwin’s mechanism of evolution? Descent with Modification
This image shows descent with modification (evolution). -Mike
12. Explain the evolution of Drug Resistance in bacteria in terms of natural selection.
13. Define the following terms: a. Homologous structures Structures similar between species because they are derived from a common ancestor. b. Vestigial structures Structures that serve little or no purpose, these structures served our ancestors. c. Analogous structures Structures that look similar and serve a similar purpose, but they do not share a common ancestor. -Dahlia M.
14. What is biogeography and why is it important to the study of evolution? The geographic distribution of species. Can find fossils of very similar form on the cost of continents that used to be together
Ryan H
15. How do the fossil record and sedimentary rock provide evidence to evolution?
